This is the FJD Motorsports Blueberry tire sauce and traction additive. Works very well on high bite, hard packed clay or dirt based surfaces.

Blue: This formula works great in most conditions and on most super-soft and soft rubber compounds or tire brand.

For best results apply to the tire with cap dauber and rub in with tire brush evenly.  The longer this prep sets in the better it soaks in and more traction is added.  Time it based on where you race in the race program as too how much traction you want.
